Specification of Letters Patent.

Application tiled May 27, 1910. Serial No. 563,706.

Patented Dec. 1S), 1911.

To all whom 'it may concern:

Be it known that I, Eowann Pnnrensnoasr, a citizen of the United States, and resident of St. Louis, Missouri, have inven'ted certain new and useful Improvements in Boxes for Street-Valves, Fire-Plugs, and the Like, of which the following is a specification containing a full, clear, a'nd exact description, lreference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in a truncated box or housin lwhich is located immediately below the surace of the ground and is adapted to inclose the valves of water mains, fire plu vs and the like, the object of my invention being to construct a'fsec- .tional box'which maybe readily set up at a point Where the saine is to be used, whichv box is light and strong and not subject to `decay and is so constructed as to be put together without the use of nails,` bolts orsmilar fastening devices.

My present invention is an improvement over t-he boxes heretofore patented b v me by Letters Patent #945,596 and #945,597 patented January 4, 1910.

For the above purposes my invention consists in certain novel features of construction and arrangem nt of parts :is will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, in which:

Figure 1 is a'perspective view of my iniproved box set ip for use; F ig. 2 is a cross section ofthe l ox as the same appears when in position for use; Fig. 3 is a perspective view, with parts broken away, of the ends of two of the upper slabs or plates which I employ in the construction of my box; Fig. 4 is a similar view of the ends of two 'of the lower plates or slabs; Fig. 5 is av front elevation of the outside face of one of the up er slabs; Fig. 6 is the inside face of the sla illustrated in Fig. 5; Fig. 7 is a. section Vof one 'of the u per lates or slabs showing its method o rein orcing; Fig. 8 is a section taken on the line 8-8 of Fig. 7; and Fig. 9 is a View, partly' in section, of one of the lower plates or slabs which I employ in the construction of my box.

Referring by numerals to the accompanying drawings: 1', 2, 3 and 4 indicate the slabs or plates vwhich form the top section or .course of the box.

5, 6, 7 and 8 indicate the four slabs or plates which constitute thc lower cours;l or section of the box.

The Slab l. is provided, on on(` end. with a recess 9 and lying above said recess El is a beveled projection 1U and below said recess is a projection 11. The opposite cud ot said slab or plate 1 is provided with a tongue 12 and a` recess 13. that is to .say the cud of this plate below this tongue is cut awa)1 so as` to form the recess. thc cud of this plate above the tongue 1:2 is beveled as at 14.

Formed on the .bottoni edge of the plate 1 is a projection 1:3. Each of thc plates 2. 3 and 4 constructed like plate 1 as hercl ofore described` that` is, each of these plates or slabs has on oneofits ends :1 recess and `a beveled face lying above said recess and on its opposite end a tongue and a beveled the plates are assembled to form the top section or course of the box. as illustrated in Figml, the beveled faces or end portions of the plate will abntagainst cach other and brace each other against inward movement, as it is readily appare-ut from Fig. l, when these slabs are assembled that each end of each slab would be braced against inward movement by its own beveled ends abutting against the beveled ends of the adjacent plates.

Referring to the plate 5, which is one of the plates of th'.` lower course. this plate has formed on one enda recess 1o and below said recess is a projection 1T and above said recess is a projection 1S, the opposite end of said plate is provided with a taphring tongue 19. Formed in each ot' the plates 5, 7 and 8 is a central recess 20 adapted to receive the projections or lugs 15 formed on the lower edge of the top plates. Each of the plates 5, G. 7 and 8 is constructed alike and each has a lower beveled edge and when assembled foi-1n the lower course or section of the box. The top edge of each plate at each corner projects trated in Fig. 9, the reinforcement projecting into the extension and lugs of said plate so as to strengthen same. The plates which form the top section or course are doubly reinforced, the top portion being reinforced by woven wire or expanded metal as illustrated, the wire extending into the beveled end portions, and likewise by rods which project into the beveled end portions and the lugs.

As heretofore stated the plates which form the top course or section of the box are constructed alike and the plates which form the lower section or course of the box are constructed alike and when assembled occupy the positions as illustrated in Fig. l, the beveled ends of the top plates abutting against each other to keep the plates from tilting or bein forced inwardly and the bottom portion o? the upper plates resting against the shoulders 21 formed bv assembling the lower plates in an inclined position.

From such a construction it will be seen' that the,upper plates are prevented from inward displacement relative each otherby the packing of the dirt around the boi:4

when it is set in the ground and said plates are maintained against displacement from the lower plates by the projections 15 rest ing in the recesses in the top edge of the lower plates and by the shoulders 21.

From the foregoing description it will be seen that my improved box is formed of a series of separable plates which can be easily assembled to form the box and, when so assembled, form practically a selfcontained box.

1. The herein described truncated box for street valves and tire lugs, comprising a base section formed OP four plates of reinforced concrete, each of which plates has tapering ends and is provided on one end doxfced concrete, each` plate end a tapering projection and a beveled with a Haring recess and on the o positc end with a tapering projection, eac plate provided on its to edge with a recess intermediate its en s, a top section coniposed of four plates of reinforced concrete provided with tapering ends having bottom ed es of the same length as the to edges o the plates of the base section, eacli plate of the top section being provided on one end with a recess and a beveled rtion above said recess, and on the opposite end with a tongue and a beveled portion above said tongue, and on its bottom edge with a projection adapted to be seated inll.1 corresponding recess of the plate'nn which it is positioned.

2. The herein described truncated box for street' valves, fire plugs, and the like, comprisnga. base sect1on vformed of four plates of reinforced concrete, each of which plates has tapered ends and is provided on one end wlth a flaring recess and on the opposite end with 4a.` tapering projection, the

ledge of one plate at each corner rejecting above the edge of the adjacent p ate, a top section" composed of four4 lates of reinaving on one face lying above said projection, and on the opposite end a flaring recess and a beveled projection above said recess, the 4recess and `projection of each plate lying below the eveled portion of each plate, said plate and top section when assembled having one edge projecting below and abutting against the projecting edge of the plates of the lower section.

In testimony whereof, I have signed my name to this specification, in. presence of two subscribing witnesses.

EDWARD PRENDERGAST.
